As of aardools 0.7.3 category pages and category links are deliberately
excluded. This helps reduce processing time and size of resulting .aar files,
as well as results in cleaner article formatting, but removes the alternative
way to navigate Wikipedia that categories provide. We will consider adding
category support in the future, either by including category pages and links
as is, or by providing a dedicated category browsing interface.
